Condensing tankless water heaters designed with water ef ciency, comfort in mind Navien's Premium Efficiency Advanced condensing tankless water heaters, with ComfortFlow technology, are designed with efficiency of water usage in mind. Because the technology provides a buffer tank and programmable re-circulating pump inside the unit, the call for hot water is imme- diately satisfied. No longer does the end user need to send those precious 12,000 gallons of water down the drain while waiting for hot wa- ter to reach the fixture. CHECK OR CIRCLE #130 Tankless tempering system provides tepid water on demand Bradley's new Keltech Tankless Tempering Systems deliver instantaneous ANSI-required tepid water to emergency safety showers and eye/face washes. Drawing energy only when needed, the water heaters are designed to be highly efficient and precise in supplying tepid water at a second's notice — even in the most extreme and challenging work environments. Installation only requires one electrical con- nection and a cold water line, saving labor time and additional costs. In addition, utility costs are mini- mized because there is no need to keep a 300-gallon tank heated at all times. All models are precision-engineered with materials, such as copper tubing and robust brass castings, which exceed the standards of any application. CHECK OR CIRCLE #129 TRIANGLE TUBE'S CONDENSING BOILERS BOAST ADVANCED CONTROLS, SIMPLE CONNECTIONS Triangle Tube's Prestige Condensing Boilers with TriMax control combines advanced features with an unmatched ease of use. The 60-second setup simplifies boiler installation and provides only the options appropriate to the application. This not only allows installers to complete most setups in less than a minute, it minimizes the potential for errors. The boiler features easy connections to piping, venting and wiring. New polypropylene venting connections eliminate corrosion and provide quick access for combustion analyzers. Electrical connections are made to a clearly labeled, fixed terminal strip with individually fused high- voltage connections. Low- and high-voltage connections and wiring are separated to minimize interference. CHECK OR CIRCLE #126 BOSCH THERMOTECHNOLOGY EXPANDS BUDERUS BOILER OFFERING Bosch Thermotechnology's Buderus brand GB162 gas condensing boiler is now more versatile. Combining condens- ing and cascade technologies together in one compact, lightweight design provides ultra-high performance efficiencies (up to 93 percent AFUE) with the ability to fit multiple boiler units into tight spaces. The GB162 is ideal for wall- or rack- mounted applications for multi-boiler cascades — up to 8 units can be cascaded. The boiler is equipped with a patented, extremely efficient aluminum silicate ALU-Plus condensing heat exchanger to ensure the longest possible operational life. Each unit can modulate down to 20 percent of total output for year- round efficiency. CHECK OR CIRCLE #127 HYDRONIC SYSTEM CONTROL MAXIMIZES EFFICIENCY OF MULTIPLE BOILER TYPES AND SIZES Cleaver-Brooks' Hydronic System Control is an expandable, multi-faceted solution with the flexibility to handle any type of hydronic heating system. This includes low temperature (condensing), high temperature (non- condensing) or hybrid systems designed to leverage the advantages of both technologies. The HSC's independent firing rate control maximizes the operational efficiency of the entire system, recognizing the unique operational characteristics of both con- densing and non-condensing boilers. In addition to controlling up to 20 boilers in a single system, the HSC can manage multiple pumps, valves, dampers and draft controls while supporting outdoor reset, setback and two demand priority loops. It can be applied to new or existing sys- tems and is compatible with any manufacturer's hydronic boiler. CHECK OR CIRCLE #128 hydronics products/ BELIMO ENERGY VALVE A SOLUTION TO SOLVE LOW DELTA T SYNDROME Belimo Americas has extended its energy valve range and now offers 1/2-2 inches; the complete range offering is from 1/2- to 6-inch valve sizes. The Belimo energy valve is a two-way pres- sure independent control valve that optimizes, documents and proves water coil performance. Using its Delta T Manager, the energy valve solves low Delta T syndrome by monitoring the differential temperature across the coil and adjusting the flow to maintain design Delta T set-point. This keeps the heat transfer of the coil optimized while maintaining comfort.
